And I differ a bit with your reasoning. Follow the rules because most passengers believe they must be important? Not because, say, the airline thinks they must be important?
I mean if rules say you need to report your fellow Uighurs, you should follow them because other will?
If everyone reports on their fellow Jew/Uighur, you should follow along? I mean not doing so might cause distress to your neighbor.
I'm not interested in this particular case, but in general.
At some point we have to put a cap on how much we value other people's feelings. There are neurotic personality types that by nature literally make up asinine things to worry about, and you'd have to run an infinite treadmill conforming to their nonsense. Empathy is an important value but its not an idol to be worshipped, and it should not be a rhetorical superweapon.
